Cedar Pocket Road runs through the middle of Beaver Dam Mountains Wilderness Area, a BLM managed section of land in the north west corner of Arizona, running along I-15 and the Virgin River Gorge.
Beaver Dam Mountains Wilderness Area is not open for camping, however, Cedar Pocket Road itself, along with several feet on either side, is not part of the Wilderness Area, and thus is open for camping.
About a 1/4 mile up the road from I-15, there are a few clearings where RVs can park and set up camp. If you attempt to go further up the road, it gets far more bumpy, rises steeper in elevation, and becomes more fraught with gravel. You’ll need a 4WD drive vehicle and high ground clearance to get an RV up there.
The normal 14-day BLM dispersed camping limit applies here.
You’ll also find cattle grazing through here. It seems a local rancher has grazing rights here. Though it doesn’t mean the general public cannot camp here, you’ll have to respect the cattle and avoid interfering with them, otherwise the BLM can remove you if complaints are filed.
The BLM rules state that you cannot camp within 200 feet of a body of water, which would include the Virgin River itself. The campsites along the first 1/4 mile of Cedar Pocket Road are well far away from the Virgin River. However, one particular BLM official has been known to cite campers for being too close to the river, claiming that the rule is actually “a quarter mile from a body of water”. These campsites are actually more than a quarter mile, and closer to a half mile. Keep this in mind should BLM officials try to shoo you away citing that rule.
Otherwise, expect quiet and peace camping along Cedar Pocket Road. Verizon 4G signal comes in pretty good here too.
Along the other side of I-15 is a developed campground, Virgin River Recreation Area, an campground run by the BLM. There are trash cans there you can dump your trash at. However, there is no fresh water or dump.
